SDI-DEBUG APPARATUS Application fled lay 8, 1929. Serial llo. 860,086.

This invention relates to a soldering apparatus which is especially adapted to solder dispensing outlets, such as screw to spouts or nozzles onto tin cans. Hereto ore the dispensing outlets have been manually soldered to the can bodies. A previously tinned spout or nozzle was placed in posltion on the can by the o rator who then applied a soldering iron w ile retaining the nozzle in position on the can and thereafter he removed the iron from the can and chilled the I solder, and he then removed the retaining means. Othermanufacturing methods have been tried but with little success, for this operation must be performed without burning or marl-ing the can, and the use of gas jetsor similar apparatus frequentl mars the product. Great difliculties also ave been encountered in the use of electric irons, even when the entire operation is manual due to the fact that the irons chill rapidly and must remain in contact with the can a considerable length of time, thereby causin a loss of time. It is evident, of course, t at hand operations necessarily are slow and therefore this operation of soldering the spouts onto the can is costly when compared to the manufacturing cost of the entire can, especially in view of the fact that the can bodies are formed entirel by automatic machinery. The primary 0 ject of this inven tion, therefore, is to provide an apparatus which may function automatically in soldering the nozzles or other dispensing outlets onto the cans in such a manner as to prevent any burning or mutilating of either the can or outlet'and while doing so operate at a com aratively high rate of speed. One 0 the objects of this invention is to provide an apparatus which will solder previously formed dispensing outlets such as nozzles or screw tops on tin cans without necessitating any manual operation upon either the can or outlet. Another object is to provide a soldering apparatus which is adapted to take the can from a belt conveyor such as usually is used in connection with the discharge of the cans from the can body forming apparatus and then solder a dispensing outlet on each can anddischarge the finished can from the apparatus without necessitating the use of manual labor. An-

.other object is to provide a soldering apparatus of such construction that the cans may be accurately positioned in such a manner that nozzles or other dispensing outlets may readily be brought into alignment with a previously formed 0 ening in the can body and then be soldere onto the can. A further object is to provide an apparatus adapted to solder dispensing outlets or handles or the like onto a can body, the apparatus being adapted for use in connection with cans of various shapes and sizes. Another object of the invention is to provide an apparatus automatic in operation and which is adapted to solder dispensing outlets, handles or the like on can bodies and which may utilize an electric soldering iron for the soldering operation.

Other objects of my invention will herein'after become apparent from the following description which refers to the accom anying drawings illustrating a preferre embodiment thereof, and the essential characteristics thereof are summarized in the claims.

In the drawings Fig. 1 is a plan of an embodiment illustrating a preferred form of my invention. Fig. 2 is a vertical section indicated on the line 22 of Fig. 1. Figs.

3, 4, 5, 6, 7, 8 and 9 are fragmentary vertical cross sections illustrating the apparatus at different stages of operation, these sections are indicated by the lines 33, 4-4, 5-5, 66, 77, 88, and 9-9 respectively. Fig. 10 is a horizontal section illustrating a form of can body holding means as indicated by the line 1010 on Fig. 2. Fig. 11 is in detai partially in section, of the solderin irons and certain of its associated parts. Fig. 12 is a side elevation of the iron shown in Fig. 11 but in a different operating position. Figs. 13 and 14 are horizontal sections indicated by the lines 1313 and 14-14 on Fig. 11.

My invention contemplates the provision of a series of coordinated mechanisms adapted to magnetically lift a previously formed part from a suitable conveyor, carry the part into contact with a flux applicator, then lower the part into a container of molten solder. Can bodies are then fed to mechanisms and accurately positioned and gripped thereby in a predetermined relation to the arts. The mechanism then bring the parts in contact with the can bodies and suitable electrically heated irons are provided to keep the solder melted until a weld between the part and the body has taken place at which time the joint is cooled and the product is discharged from the mechanisms.

In the embodiment illustrated I have shown eight of these mechanisms thereby causing t e apparatus to operate on eight cans at the same time some one of the aforementioned operations being performed on each can. It is contemplated, however, that more of these mechanisms may be used to increiaase the output of the apparatus as desire As illustrated in the drawings the preferred embodiment of my apparatus comprises a feeding mechanism generally indi- 25 cated at which is adapted to feed can -bodies 12 which are carried by a continuous belt conveyor 15 of the usual type, which is employed to convey the can'bodies away from the .can body forming a paratus. The feed ing mechanism 10 is adhpted to operate in timed relation to the soldering apparatus generally indicated at which comprises a series of coordinated mechanisms 23 each adapted to receive. a dispensin outlet or other part and solder it to a can Taody. Dispensin outlets which have previousl been forme may be supplied by a rotary isc 21 upon which they may be placed either by hand onby means of any suitable conveyor. A continuous belt conveyor such as indicated at 22 may be used to carry the finished product from the soldering apparatus.

Briefly the referred form of soldering apparatus, whic is illustrated in the accompanying drawings comprises a table 30, havmg circular shaped top portion 31, which is supported by le 32 and suitable cross members 33. The ta le may be provided with rails or raised portions 34 along which the cans may be carried. The can bodies 12 are carried to the apparatus by a belt 15 and may abut a positive stop 16, which is adapted to retain the can bodies in a position where they may be forcedacross the conveyor belt onto the raised portion 34 of the table 30 by means of a plunger bar 17. The frame 30 may also support a rotary operating head 35 comprising a series of coordinated mechanisms 23, adapted to pick up reviously formed dispensing outlets, one orm of which is indicated at 14.

The outlet 14 may be held by one of the mechanisms 23 of the rotary head and partiall emersed, first in a flux as illustrated ifi Rig. 4 and then in molten solder as illustrated in Fig. 5. The outlet 14 is then carried b the rotary head into the position illustrate in Fig. 6 where it is directly above a previously formed openin 14a in a can body 12, which has been supplied to the table 30 by the conveying mechanism 10. The can body is then accurately positioned with reference to the outlet and is swe t along the raised portion by the head 35. oth the can bodies and the outlet members are carried by the head at the same rate of speed, the outlet member 14 being directly over the opening 14a in the can body. The outlet member is then caused to be lowered into a position in contact with the can body as for exam le Fig. 1.

Suitable soldering irons such as indicated at 36 and which may be heated by means of individual electric heating units, are included in the mechanisms 23 carried b the rotary head 35. These irons are cause to contact with the outlet member immediately after the latter is picked up by the mechanisms 23 thereby centering the outlet member with respect to the rotary head. The irons 36 are adapted to heat the outlet member while the latter is being subjected to the flux and molten solder. The tips of the soldering irons are permitted to dip in the molten solder when the latter is applied to the outlet member in order that they may be properly tinned and to maintain the outlet member in its tion with res t to the head 35. The irons are held in contact with the outlet member until the latter has reached its position in its respective can bod' and until the solder on the outlet member as fused with that on the can body. Suitable means are then fporovided to-withdraw the soldering irons m contact with the outlet member, the latter being retained in position on the can by the mechanisms.

A jet of cold air may then beforced on the joint between the can andthe outlet member, chilling the solder and securing the outlet member-to the can. The outlet member may then released from the mechanism and subseguently the can body may be released and ischarged from the soldering apparatus onto a suitable conveyor such as is indicated at 22.

The soldering apparatus and its associated mechanism will now be described in detail: Mounted on one of the frame members 33 is a motor 40, which cooperates with a gear reduction unit indicated at' 41 to drive an idler gear 42, which in turn meshes with a driving gear 43, rigidl secured to the lower end of a vertical sha t 44. The shaft 44 may be rotatably supported by means of bearings 45 carried by a centrally located boss in the table 30. The bearings 45 preferably lie substantially below the surface 31 of the table. The shaft 44 is adapted to carry a rotating head 35 which supports the mechanism 23. The

head 35 may comprise a pair of spiders 48 and 49, which are drivingly secured to the shaft 44. The spider 49 ma be secured to threaded portion 44a of the s aft 44 in such a manner that it may be raised or lowered to adjust the head for diiferent heights of can bodies. Lock nuts 49a may act to retain the spider 49 in position on the shaft 44.

The spider 49 may have a plurality of outwardly extending arms 50 which may carry slidably mounted magnet bars 51. Each magnet bar 51 may be provided with an individual ener izing coil 52. The latter may be energized y means of wiring 53 which leads through the rotary head to brushes 54 and 55 (see Fig. 5). The brushes 54 and 55 are carried by the spider 48 and spring pressed against the stationary contact bars 56 and 57 held inplace on the stationary table 30 by a suitable bracket 58 made'of an insulating material (see Fig. 5).

The magnet bars 51 may be raised and lowered by means of a cam rail 62 rigidly secured to the-stat onary table 30. Rollers 63 are carried by slide bars 64, which are slidably mounted in the lowermostspider 48 and coact with a recess 65in the cam rail to raise andlower the bars 64. The bars 64 are provided with threaded bores 66 adapted to receive threaded members 67, which are rotatably secured to yokes 68 which carry pins 69 adapted to coact with slots 70 in one end of lovers 71 which are pivoted, intermediate their ends, to depending ears 72 on the arms 50 of the spider 49. An adjustment between the cam rail 62 and each lever 71, by'reason of the threaded connection 66 and 67, is provided so that the position of the lever 71 with respect to the spider 49 will remain constant when the latter is raised or lowered to accommodate different can bodies of different heights. The levers 71 may be connected at their outer ends by means of slots 75 in the levers coacting with pins 76 which'are adapted to pass through slots 77 in the magnet bars 51 and are pivotally connected to soldering irons 36.

It will thus be seen that as the bar 71 is raised and lowered, due to the action of the cam 62, that the lever 71 will be rocked, thereby raising or lowering both the solderin irons 36 and the magnet bar 51. It is also seen that the slide bar 64 may be lengthened or shortened to accommodate the raising or lowering of the spider 49 so the difl'erent heights of can bodies may readily be used in connection with the apparatus. 1 The soldering irons 36 may comprise a pair of hollow bars 80 which maybe adapted to retain electrical heating elements '81. The bars 80 have tips 82, preferably of copper or other similar metal which are adapted to completely encircle the outlet. member 14 (as shown in Fig. 14). In order that the different shaped outlet members may readily be accommodated by the apparatus, secure the tips 82 to the irons 80 by means of set screws 83, in such a manner that the tips may be readily replaced. The soldering irons 80 have inwardly projecting ears'85 which carry the pin 76. The irons 80 have at their upper portion a cam 86 which is adapted to coact with a cam 87 carried by the magnet bar 51 which lies between the bars 80. A spring 88 serves to retain the cams 86 in contact with the magnet bar 42.

It will be seen that when the outer portion of the lever 71 is in its lowermost position and when an outlet member 14 is retained in place at the lower end of the magnet bar 51 and such outlet member is resting upon a can body 12, that the weight of the magnet bar 51 will tend to keep the outlet member 14 pressed downwardly uponv the can body. In this position the cam members 86 and 87 are in contact with each other holding the tips 82 of the irons in close contact with the outlet member 14. It will also be seen that as the lever 71 is raised it carries with it the pin 76 causing the irons 36 to move with the pin. By reason of the slot 77 in the bar 51 the initial movement of the bar 71 will not affect the magnet bar 51. In this way the irons 36 I prefer to may be removed from the outlet member '14,

while the magnet bar 51 is retained by its weight in position on the can body until such time as the solder may be sufliciently chilled to cause the outlet 14 to be retained in place on the can body 12. A further upward movement of the arm of the lever 71 will raise both the soldering arms 36 and the magnet rod 51 which has previously been deenergized by reason of the brush 54 being out of contact with. the bar 56 which is cut away at the point. Both the bar and the irons will then be clear of the can body.

To supply the apparatus with outlet mem hers, I prefer to use the following mechanism: Mounted on the frame 30 is a rotatable disc 21 (see Figs. 1 and 3). This disc carries a plurality of bosses 90, which are adapted to retain in place on the disc the previously formed outlet members 14. The latter may be supplied to the disc either manually or by some suitable conveyor mechanism. When g a magnet bar 51 comes in position over the disc 21 it overlies an outlet member 14. At this time, the coil 52 is energized, thereby causing the magnet bar 51 to lift an outlet member 14 clear of the disc 21 and retain it in position on the lowermost surface of the bar 51 (see Fig. 3).

The apparatus for supplying fiux to the outlet member will now be described. As the head is rotated in a counter-clockwise direction (see Fig. 1) the lever 71 is rocked causing the magnet bar 51 to be lowered into a sition where it may contact with a felt roll r 100, adapted to carry a suitable soldering flux. As the bar 51 is lowered the irons 36 are likewise lowered and by reason of the cams 86 and 87 the tips of the soldering irons are brought into contact with the outlet mem- 1 portions of the outlet member will be coated with the flux.

The outlet member 14 is now in condition to be tinned or dipped into the solder. The solder may be supplied to the outlet by the following mechanism: Mounted on a stationary bracket 105, carried by the frame is a pan 106 which may contain molten solder.

The portion of the pan 106 which underlies the arms 50 and their associated magnet bars 51 is comparatively shallow as at 109, so that the outlet member 14 may be slid alon the bottom of the pan, emersed to a pre etermined height in the molten solder S. To retain the solder in the pan 106 at a predetermined temperature, the pan may be gm vided with a well portion 107 a apte to hold a comparatively large amount of solder which may be heated by an electric heating element 108. 7

As the head carries the magnet bars 51' and their associated soldering irons 36 they are caused to raise by reason of a raising of the levers 71 due to the action of the cam 65 and its associated mechanisms. This retains the outlet member 14 in a raised position where it may clear the upper edges of the solder pan 106. A continued rotation of the head 35 carries the outlet member 14 into position over the pan 106. The lever 71 is then lowered, causing the outlet member 14 to come in contact with the lower surface 109 of the solder pan 106. While in this position the outlet member is retained in place on the magnet bar 51 by reason of its being gripped by the tips 82 of the soldering irons 36. Immediately before the rotary head 35 has carried the outlet 14 to a point near the forward edge of the solder pan 106 the lever 71 is actuated by the cam rail 65 and its associated mechanism to raise the outlet member 14, so

that it may clear the solder pan. While in this raised position the outlet 14 will also clear a can body 12 which is being supplied to the table 30 by the mechanism 10.

As heretofore described the can bodies 12 which have previously formed openings. 140, may be progressed along. a conveyor belt 15 and caused to come to a stop by a stationary abutment '16, in a position where they may be forced laterally acrow the belt and onto the table 30 by means of a plunger bar 17, as shown in Figs. 1 and 2.

It is necessary that a can be fed to the table 30 at predetermined intervals of time. To accomplish this I prefer to supply the following mechanism: A plunger 1 is slidably mounted in a frame 324: and is operated on by means of a lever 110, which is oked at its upper end as at 111, and adapte to coact with a pin 112 carried by a block 113, rigidly secured to the bar 117. The lever 110 is pivotally secured intermediate its ends to a frame member 324 as at 114. A rod 115 is slidably mounted on a frame member 326 and coacts with the lower end of the lever 110 by means of a pin 116 carried by the bar 115, cooperating with aslot 117- in the lever 110. The other end of the bar 115 carries a roller 118 adapted to coact with a cam slot 119 in a rota cam plate 120. The cam plate 120 is rotata ly mounted on a downwardly projecting boss 121 of the table 30. Rigidly secured to the cam plate 120 is a spur gear 121, which meshes with the driving ear 43 of the operating head 35 of the soldering apparatus.

In the embodiment illustrated, the operating head is shown as having eight sets of mechanisms 23. It therefore is evident that a can must be fed to the table 30, eight times for each revolution of the head 35. This is readily accomplished by reason of the pinion 121, which drives the operating cam 119 of the feeding mechanism, being of a ratio of eight to one with the operating gear 43. It is evident from the foregoing description that a cam may be fed to the table 30 at any predetermined time and in timed relationshiipsto the rotation of the operating head 35. the can body 12 is fed to the table 30 it is caused to be grip ed by mechanism associated with the spi er 48 and accurately positioned with reference to. the outlet member 14, in such a manner that the outlet member 14 is held directly over a previously formed opening 14a of the can body 12 in order that a lowering movement of the outlet member will cause it to contact with the opening 14a of the can.

Immediately after the can body 12 has been gripped by mechanism associated with the spider 48 of the head 35, the magnet bar 51, which at this time is holding the outlet member 14 in a raised position, is caused to drop by reason of the cam 65 acting on the bar 71 by means of the mechanism-heretofore de scribed. This causes the outlet member 14 to be lowered in place on the can directly over the opening 14a in the can body. As shown in Fig.6 the can body 12 has a previously formed opening 14a in the top thereof, the metal adj aoent the'opening being formed into an outwardly projecting tapered flange 14b adapted to fit inside of a similar flange 14c previously formed on the outlet body 12' member 14. As the magnet bar 51 is lowered it positions the outlet member 14, so that the inner bevelled surface 1400f the outlet member contacts with the outer bevelled surface 14b of the can body. This movement also causes a lowering of the soldering irons 36' which are caused to come in contact with the outlet member 14 by reason of the cams 86 on the irons contacting with the cams 87 on the magnet bar 51, thereby causing the lower ends or tips 82 of the magnet to be drawn together enveloping a portion of the outlet member 14 in close proximit with the point of contact with the can bo y.

15 It is desirous that the soldering irons 36 be heated at all times when the apparatus is in operation. To accomplish this the bracket 58 carries continuous contact bars 90 and 57, which coact with brushes 91 and 55 slidably mounted in the spider 48. The brushes are connected to the irons 36 by means of suitable wiring 92 and 93 (as shown in Figs. 3 to 9 inclusive). It is therefore evident that the solder which has been placed on an outlet member 14 will fuse with the tinned surface 145 of the can body 12. The irons 36 may remain in cont-act, for a comparatively long part of the cycle of operation, with the outlet member 14 while the latter is in position on the can body 12, to insure proper fusing of the solder with the tinned surface of the can body. In the form illustrated I have shown this operation as consuming approximately a quarter of a revolution of the head 35. At the end of this part of the cycle of operation the lever 71 may cause the soldering irons 36 to be raised and drawn out of contact with the outlet member 14. However, I prefer to permit the magnet bar 71, which at this time is deenergized to remain lowered, resting on the outlet member 14, and retaining the latter member in place on the can body, while a Jet of cold air indicated at 125 inFig. 8 is forced against the soldered joint 140 between the can body and the outlet member.

Any suitable means may be used to su ply the air and conduct it to a position where it may be foroed in a jet upon the 'can. In the embodiment shown a tube 126 which is so positioned as to clear the moving parts ofthe head 35 and the can body 12 conveys air from any suitable compressor (not shown) to the can body. The tube 126 may be secured to the frame 30 by any suitablemeans such as the clips 127.

Immediately after the soldered joint between the can body and outlet member has become chilled, the magnet bar 71 maybe caused to raise by means of the cam 65 and its associated mechanism. The finished can 12a is then in position to be dischargedfrom the mechanism in a manner hereinafter to be described and the arm 50 with its associated mechanism is then free to enter another cycle 66 of operation.

, cam is arranged in such a manner as to The pping means for can b05 12 must be of sue a nature that the body 12 will be accurately positioned on the head so that the opening 14a and the bevelled rim 14b of the can bod will be sitioned directly below one of t e magnet are 51 and its associated outlet. member 14. A slight clearance is allowed between the bevelled surface 146 of the can body and the bev-. elled surface 140 of the outlet member, to care for small variations in size of the can bodies. However, the can bodies are so formed that variation in them seldom exceeds one or two thousandths of an inch: This of course, is readily taken care of in the clearance allowed between the outlet member and the raised portion 14b of the can body. However, it is necessary that the cans be accurately positioned in order that the outlet members may readily seat upon the flanges 14b of the can bodies. This may be accomplished by a gripping mechanism which may be associated wit the rotary head 35.

In the embodiment illustrated Ihave (pro- 4 vided the spider 48 with outwardly exten arms 130 which are adapted to substantially underlie the arms 50 of the upper spider member 49. Removably secured to each of these arms is an extension 131 which is adapted to overlie the raised portion or slideway 34 of the table 30 and underlie the solder pan 106 as well as the flux roller 100, as shown in Figs. 4 and 5.

' When the can,body is rectangular as is illustrated in the drawings the member 131 may be L shaped to contact with two adjacent sides of the can in such a manner as to restrict the inward movement of the can by a surface 132 and to force the can to slide along the raised portion 34 of the bed by reason 0 a surface 133 of the extension 131. The member 131 is shown as being removable so that it may be chan d to accommodate cans of various sizes an shapes.

To retain the can in contact with the surfaces 132 and 133 of the extension 131 I may provide a similar L shaped member 135 whic is adapted to contact with the adjacent sides of the can opposite to those which bear against the member 131 to force the cam against thelatter member. As illustrated, the member 135 may be pivoted to the arm 131 by a pin 136 and may have an car 137 adapted to carry a roller 138 which coacts wlth a cam 140 rigidly secured to the base 30. It will be seen that as the arm 130 is rotated by reason of the rotation of the spider 48 and the shaft 44 the cam roller 138.will be caused to' follow a cam slot 139 in the cam 140. This swing the arm 135. This is best illustrated in Figs. 10 and 1. .The cam slot 139 is so arranged as to separate the members 131 and 135 and hold them separated until a can, which has been forced from the conveyor 15 onto the raised 1positioning the v portion or slideway 34 of the table 30 concompleted can 12a isparried along the raised tacts with the extension 131 at which time portion 34 of the table by one of t e arms 131 the cam 140 will cause the member 135 to the lower part ofthe can contacts with the swing towards the can, forcing it into posirail 160 and a further rotation of the arm 131 tion against the faces 132 and 133 of the excauses the can to be forced outward along the tension 131.
